Watch What Happened When 'Jersey Shore' Met 'Jersey Floor'

It was a case of 'When Drootchie Met Snooki' when the 'Jersey Shore' gang stopped by NBC headquarters at 30 Rock and got to visit the totally awesome realm known as 'Jersey Floor.'

Jimmy Fallon's 'Jersey Shore' parody has been a running gag on his late night talk show since March. In Fallon's world, there's a magical floor in the office building "where you can go and everything's Jerseyfied!"

After the jump, watch what happens when the real 'Jersey Shore' gang joined J-Bro, Drootchie and the gang in "the most funnest place in the entire world!"

Taking his party posse of Rachel Dratch (Drootchie) and Higgins (The Inflation) up to party like it's August on the boardwalk, Fallon (J-Bro) has a sudden moment of doubt.

"We get in an elevator, we press a button, and we get off the floor and we're magically transformed and we have awesome clothes and awesome hair and we don't know why it happens ... and then we come back and we're totally normal. Think it's weird?" No? "I think it's freaking awesome!"

Up on 'Jersey Floor' guest B-Hole is the only guest to have qualms about the whole thing. "These people need to calm down. Seriously. We're hanging out in an office building. ... This is not fun."

But then the 'Jersey Shore' stars turn up and clubbing time is on!

Previous guests on Jersey Floor' include Fallon's 'Saturday Night Live' pals Amy Poehler and Tina Fey, who vamped it up as the new guidettes on the block.
